Titanomagnetite

I'm reading about flood basalts, and there's so many interesting words for the geological makeup of them, like phenocrysts, rhyodacites, and vesicles.

I'm such a dork.

Here, have a peek at Yellowstone's caldera's rumblings. I'm looking for something that could translate it into sound, as I think that could make for an interesting white noise generator (nature always makes the best white noise).
